Field Detail

connection

protected final AMQPConnectionContext connection

protonSession

protected final AMQPSessionContext protonSession

receiver

protected final org.apache.qpid.proton.engine.Receiver receiver

amqpCredits

protected final int amqpCredits

minCreditRefresh

protected final int minCreditRefresh

minLargeMessageSize

protected final int minLargeMessageSize

sessionSPI

protected final AMQPSessionCallback sessionSPI

currentLargeMessage

protected volatile AMQPLargeMessage currentLargeMessage

creditRunnable

protected final Runnable creditRunnable

We create this AtomicRunnable with setRan. This is because we always reuse the same instance. In case the creditRunnable was run, we reset and send it over. We set it as ran as the first one should always go through

useModified

protected final boolean useModified

pendingSettles

protected int pendingSettles
